Our verdict on Imperva DDoS Protection
Imperva DDoS Protection is a cloud-based service for organizations defending websites, APIs, network infrastructure, DNS servers, and internet-facing IPs. It covers Layer 3/4 volumetric and protocol attacks alongside Layer 7 application DDoS attacks. Protection is managed through automated detection and mitigation, with always-on and on-demand modes, flow-based monitoring, and automatic or manual switchover. It is aimed at organizations that need managed protection across both application and network environments rather than a narrowly focused website tool.
The published plan structures separate continuous protection, on-demand diversion, and contingency coverage. Always-On routes traffic continuously through Imperva and includes a 3-second mitigation SLA, flow monitoring, and unlimited diversions. On-Demand includes 100 Mbps bandwidth, flow monitoring, traffic diversion through an Imperva PoP, and diversion durations of up to 72 hours. Contingency S, M, L, and XL provide backup DDoS protection with 1,000 Mbps, 4,000 Mbps, 8,000 Mbps, and 100,000 Mbps bandwidth respectively. Their included diversion counts are 2, 3, 3, and 4. Pricing requires contact with sales.
Platform fit is a central strength. Imperva supports GRE tunnels, cross-connects, and virtual cross-connects for network deployment, while Anycast routing and real-time capacity management support traffic handling across its global scrubbing network. SIEM integration connects DDoS monitoring with security operations, and cloud WAF integration extends website protection through the Imperva Application Security platform. Organizations seeking a managed cloud service with multiple mitigation modes and WAF alignment should consider it. Teams wanting self-serve pricing, a free plan, or a simpler web-only protection product should look elsewhere.
